Description

Technical Field

[0001] This application relates to the field of aerosol generation equipment technology, specifically to an atomizer and an aerosol generation device. Background Technology

[0002] Currently, in the field of aerosol generation equipment, after the aerosol matrix is ​​heated and atomized to generate aerosols, some condensate is produced during airflow. This condensate adheres to the air passages and flows under gravity, potentially leaking outwards from the air inlet, causing leakage. Related technologies use a microporous structure for the air inlet to prevent condensate leakage; however, this structure still has drawbacks. Condensate still accumulates above the microporous structure, and as the accumulation increases, leakage will continue, negatively impacting the user experience of the aerosol generation equipment.

[0032] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods.

This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0033] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0034] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0035] The atomizer provided in this application can be assembled with a power supply component to form a complete aerosol generation device. The power supply component provides electrical energy to the atomizer, enabling it to heat the aerosol matrix and generate aerosol. The atomizer is a liquid-storage device, containing a liquid storage chamber for storing the aerosol matrix and an air guide chamber for guiding gas into the atomizing core assembly. Within the air guide chamber, a first baffle separates the air inlet channel from the air guide hole on both sides, preventing condensate generated within the atomizing core assembly from flowing directly into the air inlet channel through the air guide hole and causing leakage.

[0036] The following describes some embodiments of the atomizer and aerosol generating device provided in this application with reference to the accompanying drawings.

[0037] One embodiment of this application provides an atomizer 100, such as Figure 1 , Figure 2 and Figure 3As shown, the atomizer 100 includes a housing 1, a first sealing element 2, and an atomizing core assembly 3. The housing 1 serves as the mounting base, and the first sealing element 2 and the atomizing core assembly 3 are disposed within the housing 1. The top of the housing 1 has a mouthpiece 111, and the bottom of the housing 1 has an air inlet channel 121 that extends inward along the height direction into the air guide chamber 14. The first sealing element 2 divides the internal space of the housing 1 into a liquid storage chamber 13 and an air guide chamber 14, and the first sealing element 2 has a through-hole 21 extending along the height direction. The liquid storage chamber 13 can store an aerosol matrix. The atomizing core assembly 3 is disposed within the liquid storage chamber 13 and communicates with the mouthpiece 111 and the air guide chamber 14, for example... Figure 3 In the example shown, one end of the atomizing core assembly 3 is connected to the air duct 21 to communicate with the air duct chamber 14 through the air duct 21. The other end of the atomizing core assembly 3 extends to a position near the top of the housing 1 and is connected to the mouthpiece 111 to communicate with the air vent of the mouthpiece 111. The atomizing core assembly 3 can generate heat when powered on to heat the aerosol matrix, causing the aerosol matrix to atomize and generate aerosol. At the same time, external air can enter the air duct chamber 14 through the air intake channel 121 and enter the interior of the atomizing core assembly 3 through the air duct 21, so that the aerosol mixes with the air and flows with the airflow to the mouthpiece 111.

[0038] Among them, such as Figure 3 In the example, the first seal 2 is provided with a first baffle 22 on the side facing the air guide cavity 14. The first baffle 22 is located between the air guide hole 21 and the air intake passage 121 to separate the air guide hole 21 and the air intake passage 121 on both sides of the first baffle 22. When the condensate flows from the air guide hole 21 into the air guide cavity 14, the first baffle 22 can block and guide the condensate, preventing the condensate from flowing directly into the air intake passage 121.

[0039] It is understandable that condensate will generally adhere to the walls of the internal structure of the device and flow downwards under the action of gravity. If there is no structural barrier between the air guide hole and the air intake channel, the condensate can easily flow directly into the air intake channel from the air guide hole and leak outwards from the air intake channel. Moreover, even if the air guide hole and the air intake channel are misaligned, when the atomizer is tilted, the condensate may still flow directly into the air intake channel.

[0040] In this embodiment, the atomizer 100, through structural improvements and optimizations, can separate the air intake channel 121 and the air guide hole 21 on both sides of the first baffle 22, thereby effectively preventing the condensate flowing from the air guide hole 21 to the air guide chamber 14 from directly entering the air intake channel, thus reducing the possibility of leakage. Even when tilted, it can protect and block the air intake channel from condensate, which is beneficial to improving the user experience.

[0041] It should be noted that the number, size, and location of the air intake duct 121 and the first baffle 22 can be set according to specific usage requirements.

[0042] In further embodiments of this application, such as Figure 3 , Figure 4 and Figure 5 As shown, in the atomizer 100, the air guide hole 21 of the first seal 2 is offset from the air inlet 121 at the bottom of the housing 1 in the first direction, for example... Figure 3 In the example shown, the air guide hole 21 and the air intake passage 121 are offset in the horizontal direction perpendicular to the height direction, that is, the air intake passage 121 is not directly below the air guide hole 21. This prevents the condensate in the air guide hole 21 from dripping directly into the air intake passage 121 when it flows downward under the influence of gravity. Moreover, the first baffle 22 blocks at least a portion of the air guide hole 21 in the first direction. When the condensate flows downward along the inner wall of the air guide hole 21 to the edge of the air guide hole 21, it can prevent the condensate from flowing along the bottom surface of the first seal 2 towards the air intake passage 121, thereby keeping the condensate away from the air intake passage 121 and further reducing the possibility of condensate leaking outward through the air intake passage 121.

[0043] It should be noted that, in Figures 3 to 5 The horizontal direction shown is only one example of the first direction. Depending on the specific structural design, the first direction may also be other directions on the horizontal plane, or other directions that are inclined at a certain angle to the horizontal plane.

[0044] Furthermore, in one embodiment, such as Figure 3 and Figure 6 In the example shown, the first baffle 22 of the first seal 2 abuts against the top surface of the intake duct 121, which can eliminate the gap between the first baffle 22 and the intake duct 121 in the height direction, preventing condensate from flowing into the intake duct 121 through the gap. For example, Figure 6 In the example, in the horizontal direction, the first baffle 22 protrudes outward relative to the air intake passage 121 on the side facing the air guide hole 21. That is, a part of the bottom surface of the first baffle 22 is in contact with the top surface of the air intake passage 121, while the part near the air guide hole 21 is in a suspended state. When the condensate in the air guide hole 21 flows down along the surface of the first baffle 22 to the bottom of the first baffle 22, since the bottom edge of this side is in a suspended state, the condensate can drip directly and will not directly contact the air intake passage 121, which can further reduce the possibility of condensate entering the interior of the air intake passage 121.

[0045] Furthermore, in another embodiment, such as Figure 7In the example shown, the sidewall of the first baffle 22 away from the air guide hole 21 abuts against the sidewall of the air intake duct 121. When the condensate flowing out of the air guide hole 21 flows downwards along the first baffle 22 to its bottom edge, since the bottom edge of the first baffle 22 is below the top surface of the air intake duct 121, even if some condensate contacts the sidewall of the air intake duct 121, it will continue to flow downwards under gravity and will not contact the top surface of the air intake duct 121, thus preventing condensate from entering the interior of the air intake duct 121 from the top. Furthermore, in this embodiment, the thickness of the first baffle 22 can be appropriately reduced, further reducing space occupation and facilitating the rational arrangement of various structures within a confined space.

[0046] In further embodiments of this application, such as Figure 3 and Figure 4 As shown, the first baffle 22 is in the form of an arc-shaped plate. The center of curvature of the arc-shaped plate is located on the side closer to the air intake duct 121. That is, the side of the first baffle 22 facing the air intake duct 121 is an arc-shaped concave surface, while the side of the first baffle 22 facing the air guide hole 21 is an arc-shaped convex surface. By setting the first baffle 22 with an arc-shaped plate, on the one hand, the coverage area of ​​the first baffle 22 in the circumferential direction of the air intake duct 121 can be increased, and it can be adapted to the inner hole shape of the air intake duct 121, avoiding obstruction of the air intake duct 121; on the other hand, the structure of the arc-shaped plate can also maintain a certain distance between the condensate adhering to the side facing the air guide hole 21 and the air intake duct 121, further reducing the possibility of condensate entering the air intake duct 121.

[0047] It should be noted that the curvature, radius and other dimensions of the first baffle 22 can be set according to the specific shape and size of the air intake duct 121 and the air guide hole 21, so as to block the condensate on one side of the air guide hole 21 from flowing to the side of the air intake duct 121 to the greatest extent.

[0048] Of course, the above is only a preferred example of the first baffle 22. In practical applications, the first baffle 22 can also adopt other structural forms. For example, the first baffle 22 can be set to be bent towards the side of the intake passage 121 in at least a portion extending along the circumference of the intake passage 121. The bent portion can be an arc-shaped structure or a planar structure, which can form a barrier around the intake passage 121 in the circumference of the intake passage 121, thereby expanding the coverage area and preventing condensate from entering the intake passage 121.

[0049] Furthermore, in one embodiment, such as Figure 3 and Figure 5In the example shown, in the height direction, the edge of the air guide hole 21 facing the air guide cavity 14 has a first protrusion structure 23. The first protrusion structure 23 protrudes downward and is arranged circumferentially along the air guide hole 21. By providing the first protrusion structure 23, the condensate flowing out of the air guide hole 21 is guided, allowing the condensate to flow downward along the first protrusion structure 23, preventing the condensate from flowing laterally along the bottom surface of the first seal 2 from the edge of the air guide hole 21, thereby preventing the condensate from approaching the air intake passage 121. The first protrusion structure 23 can be, for example, […]. Figure 5 The annular protrusion structure shown can also adopt other shapes, such as an elliptical structure or a square structure, to completely seal the edge of the vent 21 in the circumferential direction. Of course, the first protrusion structure 23 can also be configured as a discontinuous structure in the circumferential direction, for example, multiple arc-shaped protrusion structures can be spaced apart along the circumference of the vent 21, which can also guide the condensate within a certain range. Preferably, as... Figure 5 In the example, when the first protrusion structure 23 adopts an annular protrusion structure, the inner wall of the first protrusion structure 23 can be set to coincide with the inner wall of the air guide hole 21, thereby further reducing the space occupied by the first protrusion structure 23, which is beneficial for spatial layout.

[0050] Furthermore, in one example, such as Figure 5 and Figure 8 In the example, in the height direction, a portion of the first baffle 22 overlaps with the first protruding structure 23, meaning that a portion of the structure of the first baffle 22 is formed by the downward extension of the first protruding structure 23. This further reduces the overall space occupied by the first protruding structure 23 and the first baffle 22. The first protruding structure 23 and the first baffle 22 can be integrally molded for ease of manufacturing. Preferably, a portion of the sidewall of the first baffle 22 extends horizontally toward the edge of the air guide hole 21. When the condensate in the air guide hole 21 flows downward along the first protruding structure 23 to the bottom edge, it can continue to flow downward along the first baffle 22. This allows the first protruding structure 23 and the first baffle 22 to work together as guides, making it difficult for the condensate to flow laterally toward the air intake duct 121, thereby further reducing the possibility of leakage into the air intake duct 121.

[0051] Furthermore, in another example, the first protruding structure 23 and the first baffle 22 are spaced apart, that is, a certain distance is maintained between the first protruding structure 23 and the first baffle 22, and they do not directly contact each other, thereby further increasing the distance between the air intake passage 121 and the air guide hole 21. For example, the first protruding structure 23 and the first baffle 22 are spaced apart in the horizontal direction. When the condensate flows downward from the air guide hole 21 to the bottom edge, even if some of the condensate flows laterally, the downward protruding structure of the first protruding structure 23 limits the lateral flow distance of the condensate, making it difficult for it to approach the air intake passage 121 under the action of gravity. Moreover, the first baffle 22 can further block the laterally flowing condensate, which can further reduce the possibility of leakage from the air intake passage 121.

[0052] In further embodiments of this application, such as Figure 3 , Figure 5 and Figure 8 As shown, the atomizer 100 also includes a first liquid-absorbing structure 141, which is disposed within the air-guiding chamber 14 to absorb condensate. This allows condensate to flow into the air-guiding chamber 14 from the air-guiding hole 21 and be absorbed by the first liquid-absorbing structure 141, preventing free flow within the air-guiding chamber 14. Correspondingly, the first sealing member 2 has a second protruding structure 24 on the side facing the air-guiding chamber 14. The second protruding structure 24 protrudes downwards and abuts against the top of the first liquid-absorbing structure 141 to fix it in place. The top surface of the first liquid-absorbing structure 141 is lower than the top surface of the air intake duct 121 to prevent the condensate absorbed by the first liquid-absorbing structure 141 from entering the air intake duct 121. The first liquid-absorbing structure 141 can specifically take the form of absorbent cotton or similar structures.

[0053] Furthermore, such as Figure 3 , Figure 4 and Figure 9 In the example shown, the first sealing member 2 has an atomizing core mounting groove 25 on the side facing the liquid storage chamber 13, and an air guide hole 21 is provided on the bottom wall of the atomizing core mounting groove 25. The bottom of the atomizing core assembly 3 extends into the atomizing core mounting groove 25 and communicates with the air guide hole 21. The shape of the atomizing core mounting groove 25 is adapted to the atomizing core assembly 3 and seals with the atomizing core assembly 3, making it difficult for the aerosol matrix in the liquid storage chamber 13 to directly enter the air guide chamber 14 through the atomizing core mounting groove 25. At the same time, the atomizing core mounting groove 25 can be used to fix the atomizing core assembly 3.

[0054] In further embodiments of this application, such as Figure 3 , Figure 4 , Figure 10In the example, the housing 1 is a detachable structure, including a split upper housing 11 and a housing base 12. The top of the upper housing 11 is provided with a suction nozzle 111, and the bottom of the upper housing 11 has an opening 112. The housing base 12 is detachably connected to the bottom of the upper housing 11, and a portion of the structure of the housing base 12 extends into the interior of the upper housing 11 through the opening 112. The first seal 2 is located inside the upper housing 11 and seals against the inner wall of the upper housing 11, thereby forming a liquid storage chamber 13 in the space above the first seal 2 within the upper housing 11, and a gas guiding chamber 14 in the space below the first seal 2. Correspondingly, the portion of the housing base 12 extending into the upper housing 11 is connected to the first seal 2 to support the first seal 2, thus keeping the first seal 2 fixed within the upper housing 11.

[0055] Specifically, such as Figure 4 , Figure 5 as well as Figures 8 to 10 In the example, the first seal 2 is made of silicone, and a sealing ridge 28 is provided on the outer circumferential sidewall of the first seal 2 to form a sealing fit with the inner sidewall of the upper housing 11. A liquid injection plug 124 is provided on the top of the housing base 12. The liquid injection plug 124 extends into the upper housing 11 along the height direction and extends to the installation position of the first seal 2. Correspondingly, the first seal 2 has a corresponding liquid injection hole 27 on the side facing the gas guide cavity 14. The liquid injection hole 27 communicates with the liquid storage cavity 13. The liquid injection plug 124 extends into the corresponding liquid injection hole 27 to seal the liquid injection hole 27. When liquid injection is required, the housing base 12 can be separated from the upper housing 11 so that the liquid injection plug 124 can be removed from the corresponding liquid injection hole 27, thereby replenishing the aerosol matrix into the liquid storage cavity 13 through the liquid injection hole 27. The injection plug 124 can be a cylindrical shape with a diameter that gradually increases from top to bottom. The shape of the injection hole 27 is adapted to the injection plug 124 so that it can form a fixed fit with the inner wall surface of the injection hole 27 after the injection plug 124 is inserted into the injection hole 27. Of course, in practical applications, cylindrical or other shaped injection plugs 124 can also be used, depending on the specific application requirements.

[0056] An embodiment of the second aspect of this application provides an aerosol generating device 500, such as... Figure 11 and Figure 12 As shown, the aerosol generating device 500 includes the atomizer 100 and power supply component 510 as described in any of the embodiments of the first aspect. The power supply component 510 is assembled and connected to the housing 1 of the atomizer 100, and is electrically connected to the atomizing core component 3 of the atomizer 100 to supply power to the atomizing core component 3, so that the atomizing core component 3 heats up when energized, thereby causing the aerosol matrix to be heated and atomized to form an aerosol.

[0057] It should be noted that the connection method between the power supply component 510 and the atomizer 100 is not limited to... Figure 11 and Figure 12 The example shown can be modified to use other connection methods as needed. Additionally, the atomizer 100 and power supply assembly 510 can be detachably connected, allowing users to easily replace the atomizer 100 with different flavored aerosol bases as required. Of course, the atomizer 100 and power supply assembly 510 can also be a non-detachable integrated structure, which will not be elaborated upon here.

[0058] The following describes a specific example of the aerosol generating apparatus 500 of this application with reference to the accompanying drawings.

[0059] like Figures 1 to 12 As shown, the power supply component 510 of the aerosol generating device 500 includes a power supply housing 511, a battery 512, and a corresponding electronic control board 513; the battery 512 and the electronic control board 513 are both located in the power supply housing 511, and the battery 512 is electrically connected to the electronic control board 513; the power supply housing 511 is detachably connected to the bottom of the atomizer 100, for example, by means of a snap fastener or a magnetic fastener, and can be disassembled and assembled as needed.

[0060] like Figure 3 , Figure 4 as well as Figure 12 As shown, the bottom of the housing base 12 of the atomizer 100 has a conductive hole 122, through which a conductive element 123 passes. One end of the conductive element 123 extends to the bottom of the first sealing member 2 and abuts against the pin structure of the atomizing core assembly 3, while the other end of the conductive element 123 extends to the bottom surface of the housing base 12. The power supply assembly 510's control board 513 is correspondingly disposed on the top of the battery 512 and abuts against the conductive element 123 of the atomizer 100 through a corresponding electrical connection structure, thereby controlling the power supply state between the battery 512 and the atomizing core assembly 3.

[0061] Specifically, the conductive element 123 includes interconnected columnar and sheet-like structures. The columnar structure of the conductive element 123 extends upward along the conductive hole 122 to the bottom surface of the first sealing element 2. A corresponding conductive assembly groove 26 is provided on the bottom surface of the first sealing element 2. The pin structure of the atomizing core assembly 3 passes through the first sealing element 2 and extends laterally into the conductive assembly groove 26 to form an abutment fit with the columnar structure of the conductive element 123. The bottom surface of the housing base 12 has a groove structure communicating with the conductive hole 122. The sheet-like structure of the conductive element 123 is located in the groove structure to facilitate electrical connection with the power supply assembly 510. Among them, the air guide hole 21 is located in the middle of the first sealing element 2. There are two conductive holes 122, two conductive elements 123, two liquid injection plugs 124, two liquid injection holes 27, two air inlet channels 121, and two first baffles 22, which are symmetrically arranged on both sides of the air guide hole 21.

[0062] like Figure 3 and Figure 12 In the example shown, the atomizing core assembly 3 includes an atomizing cover 31, a second liquid absorption structure 32, and an atomizing core 33. The bottom of the atomizing cover 31 extends into the atomizing core mounting groove 25 on the first sealing member 2 and is sealed to the inner sidewall of the atomizing core mounting groove 25. The second liquid absorption structure 32 is a cylindrical structure, and the atomizing core 33 is disposed on the inner sidewall of the second liquid absorption structure 32. The atomizing core 33 and the second liquid absorption structure 32 are disposed inside the atomizing cover 31. A liquid inlet hole is provided on the sidewall of the atomizing cover 31, through which the aerosol matrix in the liquid storage chamber 13 can flow into the interior of the atomizing cover 31 and be adsorbed into the second liquid absorption structure 32. The aerosol matrix contacts the atomizing core 33 through the second liquid absorption structure 32, and is heated and atomized when the atomizing core 33 is energized. The atomizing core 33 has two pin structures that extend downwards and pass through the first seal 2. The portion of the pin structure extending into the air guide cavity 14 bends laterally and extends into the corresponding conductive assembly groove 26, abutting against the corresponding conductive element 123. The top of the atomizing cover 31 is a tube structure that extends along the height direction into the mouthpiece 111, forming a sealed connection with the mouthpiece 111 through the second seal 4.

[0063] The power supply housing 511 is a non-enclosed structure, allowing external air to enter the air intake duct 121 on the housing base 12 through the power supply housing 511, and then enter the atomizing cover 31 through the air guide hole 21 to mix with the aerosol generated by the heating of the atomizing core 33, and drive the aerosol to flow towards the mouthpiece 111.

[0064] like Figure 4 and Figure 5In the example, the two air intake ducts 121 are located on both sides of the air guide hole 21, and both are cylindrical air intake structures; correspondingly, the two first baffles 22 are both arc-shaped plates, and are centrally symmetrically arranged with respect to the air guide hole 21, so as to separate the two air intake ducts 121 from the air guide hole on both sides of the corresponding first baffle 22. For example, Figure 3 In the example, each first baffle 22 extends along the height direction to the top surface of the corresponding air intake duct 121 and protrudes horizontally toward the air guide hole 21. The bottom edge of the air guide hole 21 has a downwardly protruding first protrusion structure 23, which is an annular protrusion structure coaxially arranged with the air guide hole 21, and the inner wall of the first protrusion structure 23 coincides with the inner wall of the air guide hole 21. The side of the first baffle 22 near the air guide hole 21 and the bottom edge of the first protrusion structure 23 guide the condensate flowing out of the air guide hole 21, so that the condensate can flow downward along the first baffle 22 and prevent the condensate from entering the air intake duct 121.

[0065] A first liquid-absorbing structure 141 is provided on the bottom surface of the air guide cavity 14, and two second protrusions 24 are provided on the bottom surface of the first sealing member 2. Both second protrusions 24 are cylindrical and extend along their height to the top of the first liquid-absorbing structure 141, thus supporting the first liquid-absorbing structure 141 and fixing it to the bottom surface of the air guide. The top surface of the first liquid-absorbing structure 141 is lower than the top surface of the air intake channel 121. When condensate flows into the air guide cavity 14 through the air guide hole 21, it eventually drips into the first liquid-absorbing structure 141. Adsorption retains the condensate within the first liquid-absorbing structure 141, preventing free flow and further reducing the possibility of condensate entering the air intake channel 121.

[0066] Furthermore, the aerosol generating device 500 in this embodiment also has all the beneficial effects of the atomizer 100 in any of the embodiments of the first aspect described above, which will not be repeated here.

[0067] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
